(3) The host can still ping Internet using LAN DHCP address

(4) The scenario will continue about 30secs.

3. Because of the memory shortage (ZW5/P1), device have to restart when customer need

to upgrade firmware sometimes.

Issues

[UPnP]

1. Sometimes on screen the “Local Area Connection” icon for UPnP disappears. The icon

shows again when restarting PC.

[Bandwidth Management]

1. Bandwidth management H.323 service does not support Netmeeting H.323

application.

2. In some cases, BWM (Fairness-Based mode) cannot manage bandwidth accurately.

Ex. In WAN interface, there are two subclasses for FTP service, their speed are

100Kbps and 500Kbps, the traffic match the filter which speed is 500Kbps may only

use half of it’s bandwidth.

[Bridge Mode]

1. Don’t use CI command “bridge rstp bridge enable” to enable RSTP, it will change the

initial Path Cost value to an incorrect value.

[Wireless]

1. Wireless client still can scan device network after disabling wireless card.

[ALG]

1. Symptom: P2002 can’t connect with each other in Peer-to-Peer mode.

Condition:

Topology: P2002--(LAN)ZyWALL_A(WAN, IP=172.21.2.151)--(WAN,

IP=172.21.1.134)ZyWALL_B(LAN)--P2002

(1) In ZyWALL_A and ZyWALL_B, add a "WAN to LAN" firewall rule to pass

traffic with port "5060".

(2) In ZyWALL_A and ZyWALL_B, add a port forwarding rule "5060" to P2002.

(3) In ZyWALL_A and ZyWALL_B, enable SIP ALG.

(4) Setup both P2002 to Peer-to-Peer mode.

(5) Making the SIP connection by P2002 will be failed.

(6) Turn off firewall in ZyWALL_A and ZyWALL_B, sometimes the connnection can

be built up if we dial from P2002 which is behind ZyWALL_A.

[Anti-Spam]

1. Mail cannot be passed through in below conditions:

(1) Through 2 devices with Anti-Spam enabled.

(2) NAT loopback with Anti-Spam enabled.

[VPN]

1. VPN rule swap does not support NAT Traversal.

2. When VPN tunnel is up with 3G as “My Gateway”, VPN tunnel will not be dropped

when 3G WAN is disconnected.

3. Topology:

PC1(1.33) --DUT---(VPN)-----ZW5---PC5(2.33)

PC2(11.33)--

PC3(21.33)--
